1 cup buttermilk
1 cup all-purpose flour
2 tablespoons white sugar
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
2 1/2 tablespoons butter, melted
1 cup fresh blueberries (I'm sure frozen would be fantastic as well)
Combine flour, sugar, baking powder, baking soda, and salt in a large mixing bowl. Whisk egg and butter into buttermilk. Pour the flour mixture into the wet ingredients and whisk until lumps are gone. Heat a large skillet over medium heat, and coat with cooking spray (or heat a griddle to 350). Pour 1/4 cupfuls of batter onto the skillet, and cook until bubbles appear on the surface and the edges look dry. Flip with a spatula, and cook until browned on the other side and cooked through (the blueberries will start to bubble on the top of the pancake when they are cooked).
